Major catastrophes can transform industries and cultures. The Johnstown Flood, the sinking of the Titanic, the explosion of the Hindenburg, the flawed response to Hurricane Katrina–each had a lasting impact. Even when catastrophes don’t kill large numbers of people, they often change how we think and behave. The financial collapse of 2008 led to tighter regulation of banks and financial institutions.

Dynatrace is proud to be an AWS launch partner in support of Amazon Lambda SnapStart. The new Amazon capability enables customers to improve the startup latency of their functions from several seconds to as low as sub-second (up to 10 times faster) at P99 (the 99th latency percentile). Today, application modernization efforts are centered on application programming interfaces and microservices that are sensitive to startup latency.

In the past few years, the complexity of systems architectures drastically increased, especially in distributed, microservices-based architectures. It is extremely hard and, in most cases, inefficient to debug and watch logs, particularly when we have hundreds or even thousands of microservices or modules.

DevOps and ITOps teams rely on incident management metrics such as mean time to repair (MTTR). These metrics help to keep a network system up and running?, a critical task that’s easier said than done. Other such metrics include uptime, downtime, number of incidents, time between incidents, and time to respond to and resolve an issue. A 2022 Outage Analysis report found that enterprises are struggling to achieve a measurable reduction in outage rates and severity.

So you want to build a REST API, but you don’t want to worry about the management burden when it comes to scaling it to meet the demand of your users. Or maybe you know your API will experience more burst usage than constant demand and you’d like to reduce your infrastructure costs. These are two great scenarios where a serverless architecture could benefit your API development.
